'I'he rotary member I3 presents a rounded `edge oil which -it is turnedthrough lapplication -machine drive by ,way of a pair of bevel wheels I1, I The shaft 20 is pivoted at 23by means cfan angular bearing 24.Projecting laterally from the head of ythe shafty 20 is a boss 22 whichhas an extension 36 thereon passing through a sleeve 35 onfthe body ofthe machine. Extension 36 has on its end a nger 31 which is acted uponin positive fashion'by an arm 33 on a shaft 39 for moving the worm 2|out of engagement with the toothed ed'ge of the rotary member I3 whenthe lever 39 is turned. A coil spring 40 within the sleeve 35 acts insuch manner on the boss 22 that it will normally maintain the worm 2| indriving engagement with the rotary member I3. Accordingly as the shaft39 is turned to and fro in reverse directions the Worm 2| will be movedinto and out of driving engagement with the rotary member I3. The shaft39 may be reversely turned by any suitable mechanism, and especiallylends itself to automatic control during the operation of the machine.

In the embodiment according to Fig. 1 the cam I acts simultaneously ontwo slides or carriages 4. Accordingly" there are also provided twoguide rails Il, II having two annular gears I3, I3, which mesh with oneanother, so that ,the rotary motion imparted by the worm 2| acts also inthe opposite sense on the second guide rail To a hook 26 on one of thetwo gears |3 there is secured a coil spring 25, which is attached at itsopposite end -to a hook 4| on the frame ofthe winding machine and whichtends to return the guide rails I|, I I into their initial positionimmediat'ely the gears I3 cease to be acted upon ,by

the worm 2|. If the engagement between the worm 2| and the annular gearI3 is to be broken, a partial rotation is imparted to the shaft 39(Figs. 1 and 3), the arm 38 then acting on the transverse member orfinger 31 of the boss extension 36 and thus rocking the shaft 20 aboutthe pivot 23, whereby the worm 2| is moved out of engagement with thegear I3.

The initial position of the guide rails II, II is determined by a stop28 (Fig. 4) mounted on a spindle 29, to which there is also secured apointer 42 co-operating with a fixed scale 34. The adjustment of thepointer 42 is eiected by means of a worm 3|, a shaft 32 and a knob 33,the worm 3| meshing with a gear 30, to which the pointer 42 ispreferably attached. The stop 28 projects i'nto the path of rotationofan arm 21 (Figs. 3 and 4) which is xedly mounted on the pivot I2 andaccordingly rotates together with the rotary member I3. The arm 21 onthe pivot |2is arrested, dependent on the angular position of theadjustable stop 28, when the rotary members I3, after being released bythe worm 2|,. are returned into their initial position under the actionof the spring 25.

In the arrangement according t the invention there is a neutral,positive or negative transmission of the degree of reciprocation of thecarriage 4 to the yarn guide rod 5 dependent on the adjustment, i. e.,the degree of inclination, of the oIf thearm 9 of the bell crankLleveris con.

trolled by the guide rail II in the manner illustrated in Fig. 1, theextent of reciprocation of the rod 5 will be greater than that of thecarriage 4, as indicated by the extreme positions of the bell crank arms6 shownI in full and broken lines in Fig. 1. If the arm 9 is controlledby the guide rail in the manner shown in Fig. 2, there results betweenthe two extreme positions of the carriage 4 and of the stud I6 on therod 5 a considerable reduction in the extent of reciprocation of thelatter. During the winding operation the guide rail II ycan be movedAgradually out of the one position, into the other. It is thus possibleto vary the degree of reciprocation of the thread during the windingoperation between a mini. mum and a maximum. In consequence it ispossible to produce on the one winding frame pirns Vof different lengthand form, such as are illustrated in Figs. 6 to 9, Without the ttingvvor removal of any gear parts. If a pirn is to be wound in which thetraverses of the thread guide gradually lessen then the guide rail willbe initially set in such position as will obtain the desired long lengthof traverse as shown, for example, by the position occupied by the guiderail as shown in Fig. 1, then by moving the rotary member I3, which isengaged by the worm 2|, in a clockwise direction the traverses of thethread guide are gradually lessened until the guide rail has becomemoved to occupy an inclined position as shown in Fig. 2, or even beyondthis inclined position. Reversely, one may start with short traverseswith the guide rail set in inclined position as shown in Fig. 1, andthen by moving the rotary member I3, which engaged by the Worm 2 I, inan anti-clockwise direction the traverses of the thread guide may begradually increased. 'I'he traverses of the thread guide may bemaintained at any particular point by maintaining the position of theguide rail, and this by holding the worm, or driving member 2|, indriving engagement with the rotary member which it is engaging, butwithout rotating the worm.

The simplicity of the device according to the invention and also itsreliability in operation will be quite obvious. It is accordinglyparticularly adapted for use in conjunction with completely automaticwinding frames.
